Please, SOS
When we have "could be true" - we don't have to try to find contrargument do we? We just need a prove, that in some scenario an argument is working. Am I right?

Actually, in this kind of question, the wrong answer is that is impossible or ALWAYS NOT true.
The other options that could be true are right, even though NOT always are true.
The best strategy here is to pick numbers, positive, between 1 and 3 such as an integer and a fraction: \(2\) and \(\frac{3}{2}\).
Hope this helps
